如何在Sprite-Kit中的某些场景中展示广告? [英] How to present ads during certain scenes in sprite-kit?

问题描述

这是我第一次使用swift和sprite-kit开发应用程序.我想将adMob集成到其中.我一直在寻找解决问题的方法，但没有成功.

This is my first time developing an app using swift and sprite-kit. I would like to integrate adMob into it. I have been searching a solution to my problem but I've had no success.

我在GameViewController.swift

override func viewDidLoad() {
    super.viewDidLoad()

    bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
    bannerView.isHidden = true
    bannerView.adUnitID = "ca-app-pub-************************"
    bannerView.rootViewController = self
    view.addSubview(bannerView)

    // Configure the view.
    let skView = self.view as! SKView
    skView.showsFPS = false
    skView.showsNodeCount = false

    /* Sprite Kit applies additional optimizations to improve rendering performance */
    skView.ignoresSiblingOrder = true

    // Create and configure the scene.
    let aspectRatio = skView.bounds.size.height / skView.bounds.size.width
    let scene = MainMenuScene(size:CGSize(width: 320, height: 320 * aspectRatio))
    skView.presentScene(scene)

    showBanner()

}

func showBanner() {
    bannerView.isHidden = false
    let request = GADRequest()
    request.testDevices = ["******************"]
    bannerView.load(request)

}

此设置可以完美地在所有场景中显示广告，但是我的问题是，如何使用NotificationCenter如何使其在MainMenuScene.swift和GameOverScene.swift上显示?这两个都是他们自己的类.

This setup displays the ad on all of my scenes perfectly but my question is, how would I be able to make it show on MainMenuScene.swift and GameOverScene.swift by using NotificationCenter? Both of these are their own class.

推荐答案

您提到过，您可以使用通知中心.

As you mentioned you can use Notification Center.

为您的通知创建一个密钥，以避免输入错误.您可以将其放置在项目中所需的任何位置(任何类或新的.swift文件之外)

Create a key for your notification to avoid typos. You can put this anywhere you like in your project (outside any class or a new .swift file)

 extension Notification.Name {
    static let showBannerAd = Notification.Name(rawValue: "ShowBanner")
 }

在您的GameViewController中，将观察者添加到ViewDidLoad

Than in your GameViewController add the observer in ViewDidLoad

NotificationCenter.default.addObserver(self, selector: #selector(showBanner), name: .showBannerAd, object: nil) // selector is the method to call

以及在您的SKScene中，您可以在需要显示横幅时像这样发布通知.

and in your SKScene(s) you can post the notification like so when you need to show the banner.

 NotificationCenter.default.postNotificationName(.showBannerAd, object: nil)

或者，我在Github上有一个帮助程序，它将使此操作变得更加轻松和简洁.

Alternatively I have a helper on Github which will make this much easier and cleaner.
